I get a version of this question all the time. I think we are all conditioned to shop for the best price. For some things, it makes sense to go ahead and buy the cheap version—like a hammer—although you still get what you pay for. Most of us are not professional contractors and using a hammer to hang pictures does not require the most expensive hammer on the shelf. In this case, It makes sense to buy a cheaper version for what you need.
I think the first thing we need to understand is that the supplement industry is not regulated like the drug industry. If you see an over-the-counter drug on the shelf—like ibuprofen for example—the name brand and the generic are going to be identical (except for perhaps the delivery system). Medicines are also regulated, for good reason, to be the exact dosage indicated on the label.
Remember, the FDA does not regulate what goes into your supplement bottle. Labeling laws only require that the supplement companies not make medical claims, but outside of that it is buyer beware.
Statistically, 80% of all Americans use nutritional supplements. The expectation is that the nutrients you purchased are going to provide your body with all the expected health benefits. These benefits only happen when the nutrients actually reach the target cells. After you ingest a supplement, your body will begin to breakdown the pill or capsule. The rate at which this occurs is called the absorption rate. Most supplements have low absorption rates as evidenced by Consumerlabs.com. The most advertised supplements, like Centrum and GNC, tend to have the lowest absorption rates. Simply, if the capsule does not get broken down in the system, no nutrients are available to get into your body.
Once the capsule gets broken down and gets into the blood stream, the next step is to make sure the nutrient gets into the cells of your body. The term for this is bioavailability. Only about 20% of the supplement companies will produce products with high bioavailability rates. As an example, minerals are better absorbed when they are chelated, which means they have 2 amino acids attached to each mineral molecule so that they get transported easily into the cell. Most nutrients also require other nutrients to synergistically help with absorption and bio-availability.
About 20% of the supplement market would be considered medicinal grade products with a high absorption and a high bio-availability rate. These are typically recommended or sold by health care practitioners for two good reasons.. liability and effectiveness. If you know exactly what is in it, you can effectively prescribe it.
So the next time you go bargain shopping for supplements you may very well be throwing your money into the wind. In this case, you do get what you pay for and when it comes to your health, get the best supplements you can buy.
